Downton Abbey's own Lady Cora herself, Elizabeth McGovern, will be singing at the Isle of Wight Festival, on June 23rd, 2012. She will preform with two acts Big Country & in her own band Sadie and the Hotheads.
McGovern, 50, will be singing with rock band Big Country, whose hits include In a Big Country and Fields of Fire.
She said: "I am thrilled to be playing with such a stellar cast of musicians."
McGovern has her own band called Sadie and the Hotheads, who are also to perform at the festival.
Tony Butler from Big Country said: "We had a tradition of working with great female vocalists such as Kate Bush and Eddi Reader in the past, so having the opportunity to have Elizabeth perform with us at the IOW is going to be really cool."
Festival promoter, John Giddings, promised to roll out the red carpet for the actress.
Mr Giddings said: "I have been a fan since Once Upon A Time In America.
"As soon as I found out that Elizabeth could sing, it was a must to invite her to play at the festival. "We will roll out the red carpet for Lady Cora."
WTG Lady Cora aka Elizabeth!
